Issue

During statup, a "Error occurred during the validation of this file" warning message appears, relating to the 'KSC_Database', typically after a new installation of KeySCAPE or a Windows update, where the Microsoft 2010 Access Driver has failed to install or run correctly.

Solution

With Microsoft Office and KeySCAPE installed, make sure none of the associated programs are running

You will need to install this as a local administrator (right-click > Run as Administrator). If you do not, it might appear to have installed but has not because it has silently failed.

Optional – You may wish to install the "Access database engine 2010 (x64) monitor", which is available from our general downloads page. This service will monitor the database engine and automatically apply the above fix if a future update to Office breaks compatibility.

Note: To resolve this issue in the long term, it is recommended that your install the 64-bit edition of Office.
